Abstract

Pb(Fe1/2Nb1/2)O3 and (1-x)Pb(Fe1/2Nb1/2)O3-xPbTiO3 ceramics were prepared by the precalcination method. Their structural and dielectric properties were investigated. The amount of perovsikte phase was increased by the precalcination and the dielectric properties of ceramics were improved. Additions of PbTiO3 were found to increase the tetragonality (c/a) of crystal lattice and Tc. In the middle region of (1-x)Pb(Fe1/2Nb1/2)O3-xPbTiO3, duffuse phase transitions (DPT) were observed.
